I have a lot of students asking me what mouthpieces they recommend when they are ready to take their playing to the next step! The benefits of upgrading our mouthpiece are tremendous. With a new higher quality mouthpiece, a student will instantly progress in their tone quality, intonation, articulations, and much more. A student model instrument usually comes with an entry level mouthpiece, which is satisfactory for maybe the first year of playing, but beyond that, a beginner mouthpiece with greatly limit their playing and performance abilities.
